what is 321 Stainless Steel Plate?
321 stainless steel plate is a type of stainless steel plate that is made from an austenitic alloy containing chromium, nickel and titanium. It is non-magnetic and has excellent corrosion resistance, making it ideal for applications in corrosive environments. It is often used in the fabrication of exhaust systems, turbochargers, and other high-temperature components.
what's the character of 321 Stainless Steel Plate?
321 stainless steel plate is a stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after welding and exposure to elevated temperatures. It has good creep strength and stress rupture properties. It also has excellent low temperature toughness and ductility.
321 stainless steel plate offers a variety of benefits, including: resistance to corrosion and oxidation, superior strength at high temperatures, excellent formability and weldability, and a low cost of ownership due to its long lifespan. Additionally, 321 stainless steel plate is non-magnetic, making it ideal for use in applications where a non-magnetic material is required.
